Visualisation of the reconstruction of the murine heart 3d structure obtained by X-ray phase-contrast tomography. (a) Surface rendering of the 3d reconstruction. Note that the flattened tissue in the center front region is slightly pressed by the wall of the plastic tube in which the heart placed during the scan. The tube has been removed by segmentation). (b) The orientation of the myofibers derived from the structure tensor, visualised as 3d streamlines (streamplot function of matplotlib) based on the 3D vector field of the structural orientation obtained by the structure tensor. The streamlines were generated by 5000 seedpoints in (b) and 1000 seedpoints in (c), respectively. Seedpoints were placed randomly in the volume. Scale bar: 1 mm.
